There was a report that the hardware breakpoints and watch points weren't reporting the debug architecture version as expected, they were reporting a version of 0 which is not defined in the architecture. This happens when running in a KVM guest if the host has a debug architecture version not supported by KVM, it in turn confuses GDB which rejects any debug architecture version it does not know about.

Applied to arm64 (for-next/kselftest), thanks!
